What's the problem?
Since the past few days images hosted on Reddit seem to be saving as webp from expandos. If clicking through to the actual image link they'll save as their original format.

It seems that it is in fact RES doing this and not Reddit. This is what an image looks like under Inspect Element with an expando opened up: https://preview.redd.it/ryp3m1tldjyb1.jpg?auto=webp&s=b76201bab1e95c2fbeeb27d8ca21d2a40668adea

The auto=webp makes it pretty obvious, and the entire element is from RES with image class "res-image-media res-media-zoomable".

I also assume it's happening because I updated RES and that update introduced this issue.

I also noticed this a while back and thought it was a Reddit thing. It's been pretty obnoxious when I want to share images on Skype, which doesn't support webp. I have to save the image, convert it to jpeg, share the jpeg, then delete it.

Can we get an option for this behavior?
